Answer :- 200rs
plz help me ​

Answer 1

Step-by-step explanation:

Profit = SP - CP

Let CP be x

Then, profit = (5/100) x

Hence,

(5/100) x = 210 - x

0.05x + x = 210

1.05x = 210

x = 200

Answer 2

First of all you know the formula then try to solve another type of this question and any problem you will message me and I can help you

Profit = SP - CP

Let CP be y

Then, profit = (5/100) y

(5/100) y = 210 - y

0.05x + y = 210

1.05x = 210

y = Rs.200
